WHEELBARROW GRASS-SEED SOWER.

SPECIFICATION forming part of Letters Patent No. 313,565, dated March10, 1885.

Application tiled July 25, 1834. (No model.)

To all whom t may concern,

Be it known'th'at I, GEORGE V. H. WHIT- BECK, a citizen of the UnitedStates, residing at Phelps, in the county of Ontario and State of NewYork, have invented new and useful Improvements in WheelbarrowGrass-Seed Sowers, of which the following is a specification.

The main objects of my invention are, first, to provide a frame whichshall be stiff and rigid in its construction, which shall also bedurable and hold the operating mechanism, even after long wear, inperfect adjustment, allowing compensation 0r take up for wear, and whichshall at the same time be lightand portable, also allowing the seed-boxto be placed much nearer the ground and wheel than usual; second, a verylight and strong skeleton double-hub canrwheel to operate thedistributer.

Referring to the drawings accompanying this specification, Figure lrepresents a side elevation of my invention; Fig. 2, a top View; Figs. 3and 4, enlarged views ofthe cam-hubs and connections. I

The same letters of reference refer to like parts in all the views.

A A is the frame of the machine, which I form of wroughtiron gas-pipe ofsuitable size. B B are reduced T-connectors, into the large rear ends ofwhich are screwed the wooden handles CO, and into the reduced Ts on theunder side of the legs D D, also of gaspipe. This construction permitsthe legs to be turned up into a horizontal position or unscrewed fromthe coupling, or the coupling with leg and handle attached can beunscrewcd from the side bars for convenience in storage or shipping, asthe case may be.

At E a V-shaped bend is made .near to the wheel in the gas-pipe frame onboth sides to receive the seed-box F, thereby bringing the latter nearerthe ground and placing the weight thereof and its contents more upon thewheel. At the front of the machine are screwed the the reduced elbows GG, into which is screwed, with a right-hand thread upon one end andaleft-hand thread upon the other end, a piece of gas-pipe, H, serving thedouble purpose of rigidly holding the two sides of the frame togetherand forming an axle upon which the Wheel I and its cam-hub J turn. Itwill be seen by this construction that the front end of the frame isheld in a very rm and rigid manner, and that by a slight turn of theaxle the frame can be drawn together and all wear or slack between itand the heels of the wheel is easily taken up, also permits the axle tobe l unscrewed from the elbows and the wheel easily removed forconveniece in storage or shipping. The cam is what I term adoubleskeleton hub-cam. It consists simply of the hubs K and Kon eitherside, (there being no metal between,) the six spokes connecting each hub(or twelve in all) to the two rims ot' the cam, the rims being united atevery alternate spoke by short studs, thus combining i-n one cast-ingthe hub of the wheel and a double skeleton cam of exceeding lightnessand strength. Radiating from the cam and cast therewith are the twelvewrought-iron spokes 0f the wheel, which at their outer ends are rivetedto the wrought-iron rim of the wheel I. Operated by the cam is theshake-lever O, pivoted upon the thumb-bolt P, which passes through itand the supporting-bracket Q, which is fastened to the side frame andcross-piece M. The rear end of the shake-lever is connected by a shorthook, R, to the seed-dis tributer, to which is im parted thereby a rapidbackward and forward motion. rIlhe length of stroke imparted t-o thedistributer, and consequently the amount of seed sown to the acre, isregulated by changing the fulcrurn thumb-bolt P into aseries of holes inthe shake lever O and bracket Q. On the front end of the shake-lever,which engages with the cam, I place a small friction-roller of hardmetal, either chilled iron or steel. It will be seen that thisconstruction gives a very direct, short, and positive connection bymeans of the shake-lever between the operating hubcam and theseed-distributer, by which slack or lost motion is obviated.

I am aware that wrought-irongas-pipe has been used for the frame-work ofagricultural implements before, the use of which, broadly, therefore, Ido not claim.

I am also aware that cams have been usedv upon the running-wheels ofgrass-seed sowers and other implements for the purpose of operating thedistributer; but these have hitherto been fastened to the wheel to agreater or less extent by bolts, screws, or rivets, and

ICO

therefore inoperative in a short time.

hence liable to become loose or detached, and In my invention the huband cam is one single casting, and these difficulties are entirelyobviated. I t is also a double cam placed on one side only of the wheel.The use of the V-shaped depressions in the side bars, A A, is not merelyto bring the seed-box nearer the ground, (for I am aware that in someimplements it is brought much nearer, although in a different manner,)but more particularly to provide a new, rigid, and substantial holderfor the seed-box, corresponding in form thereto and holding it inposition Without the necessity of fastenings by bolts, screws, orotherwise, which are required when the box is placed upon the top of theframe, as in the old method. The V-shaped depressions also permit thebox to be brought down into the body of the frame, relieving themachineof topheaviness, which defect exists in machines where the box is placedupon the top of the frame.

What I therefore claim as my invention, and desire to secure by LettersPatent, is-

In a wheelbarrow grass-seed sower, the double skeleton cam-hub J K K',made in one single casting placed on one side of`the wheel, with whichalso the spokes of the wheel I are cast, forming a stif and durableWheel, upon which the machine runs, and by which said double skeletoncam the shake-lever O is operated, all in combination with the axle H,elbow connectors G G, and side bars, A A, substantially as described.
